A new recursion relation for tree-level NLSM amplitudes based on hidden zeros
Xiaodi Li, Kang Zhou
In this note, we propose a novel BCFW-like recursion relation for tree-level non-linear sigma model (NLSM) amplitudes, which circumvents the computation of boundary terms by exploi…

Hidden Zeros and -split via BCFW Recursion Relation
Bo Feng, Liang Zhang, Kang Zhou
In this paper, we provide another angle to understand recent discoveries, i.e., the hidden zeros and corresponding 2-split behavior using the BCFW recursion relation. For the hidde…

Note on hidden zeros and expansions of tree-level amplitudes
Hao Huang, Ye Yang, Kang Zhou
In this note, we derive and interpret hidden zeros of tree-level amplitudes of various theories, including Yang-Mills, non-linear sigma model, special Galileon, Dirac-Born-Infeld,…
